"The motor convoy came under mortar shelling by Islamic State terrorists in the province of Deir ez-Zor. As a result of shelling, one serviceman was killed and another one was badly wounded," the ministry said. "The wounded serviceman was promptly taken to hospital but died of deadly wounds, despite efforts taken by medics."
